They may have moved on from their relationship with Playboy's Hugh Hefner, but Holly Madison and Kendra Wilkinson still have his back.

The two former "Girls Next Door" stars were livid when they heard that Hef's ex-fiancee, Crystal Harris, was trying to take back the Cavalier King Charles spaniel puppy she initially handed over to Hefner after she called off their June wedding.

At the time, Crystal gave Hef the dog because “she thinks he’s happier here," Hefner tweeted June 20. "I appreciate it, because I really missed him."

According to the Wall Street Journal, two young stars have the hottest haircuts of the year: actress Emma Watson and singer Justin Bieber. The paper has dubbed their hairstyles the "Most Influential" of 2011.

The network announced Tuesday that their popular new series is officially on for another round. The railroad drama is the second-highest rated series on AMC, after zombie fest “The Walking Dead.”

“Hell on Wheels,” set in the post-Civil War era, stars Anson Mount as a former Confederate soldier and rap artist Common playing a former slave. The two men work together on the first transcontinental railroad amidst the chaos of the changing country.
